I'm working with a couple of nutritional supplement manufacturers that want to be able to monitor environmental conditions like temperature, humidity and dust levels. Separately they also want to have a fingerprint scanner that employees will use to clock in and out for attendance.

I've taken an Arduino Yun, connected a temperature/humidity sensor to it and have that data feeding real-time into a table in OpenERP via XML-RPC. The next part is to setup the fingerprint scanner to connect to the attendance feature in the HR module.

I'm curious if there's interest for a larger community project to generically connect an Arduino to Odoo/OpenERP. Maybe a configuration screen where we can make the associations between pins on the Arduino and fields in ERP.
